Rootsioch creeping, about the thickness of a goosequill, and with the 

 short stipe closely covered with black, acuminate, finely reticulated 

 scales. Fronds scattered and erect, one to 2 feet long, by one to 2 

 inches broad, smooth, coriaceous, lanceolate, attenuated at the base; 

 while near the point on one side is a sinus, with a proliferous bud at 

 its base, arising from the side of the costa, beyond which the frond 

 terminates in a short tail-like acumvnation, about half an inch in 

 length. Sori approximate, and commonly occupying only the upper 

 half of the frond, but sometimes continuing down to the base, the 

 sporangia becoming confluent. Indusium coriaceous, entire.
